Geomorphic impact of historical slate mining activity on gravel-bed streams

Original language description

Individual sediment inputs of coarse material may affect downstream channel geometry, morphology, and grain sizes of bed sediments. This study deals with the geomorphic interactions of artificial sediment inputs in the forms of large slate dumps and adjacent gravel-bed mountain streams (Nízký Jeseník Mts, Czech Republic). The dumps were composed of coarse slate slabs up to 500 mm in diameter, whereas local streams usually contained cobbles and gravels in plane beds and riffles, and much finer sand, silt, and clay fractions in pools. The parameters of bankfull width, and bed grain sizes, here represented by mean boulder diameter as an arithmetic mean of five largest bed particles, were investigated in short intervals within four longitudinal profiles of first- to fourth-order streams influenced by historical slate mining. Coarse sediment supply from investigated dumps in low-order channels i) often transformed channel-reach morphologies (pool-riffles to plane beds), ii) significantly altered downstream calibre of bed sediments, and iii) decreased the bankfull width near the points of active sediment inputs.
